What purpose do blinkers serve?
Blinkers are a piece of equipment that look like a hood with large cups over the rear of the eyes. They are designed to limit the vision of the horse to what he / she can see in front only. They help a horse concentrate, and are used for horses that have obvious problems concentrating. Horses that will duck and dive at things they see in their periferal vision. You can have full cup blinkers (which obviously still allow for forward vision) or the cups can be cut back to allow wider vision. Sometimes holes are cut in the cups to allow a horse to see other horses coming at him / her (in a race). Saint Liam wore blinkers.
